Auto merge of #24133 - paulrouget:userAction, r=jdm
Do not allow XR session on non user-activated events This sets the thread in "user interaction mode" when the dispatched event is trusted. I also tried an approach where we would not rely on the dispatched event but just set "user interaction mode" when we get a compositor event (which, we can assume, are only user generated). That worked as well. Fixes #23787. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/24133) <!-- Reviewable:end -->
